This invention relates to new and useful improvements in scaffolds andmore particularly to an adjustable horse for scaffolding adapted for useby carpenters, plasterers, brick layers, painters, and other types ofworkman whose requirements of work are more or less similar.

The primary feature of this invention is to provide a device of thecharacter referred to which is adjustable vertically in a minimum timethereby chan ing the elevation of a platform or the like which thisdevice is adapted to support.

Another important feature of this invention is to provide a device thatis neatly folded or collapsible into a relatively small article whichoccupies very little space when stored or shipped.

A further important feature of this invention is to provide a portablescaffold that is light in weight, and can easily and quickly beassembled or disassembled.

A still further feature of this invention is to provide a device of thecharacter referred to that is strong and durable in construction,efficient and reliable in operation, relatively inexpensive tomanufacture and otherwise well adapted for the purposes for which thesame is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a perspective View of the scaffold horse constructed inaccordance with the present invention;

Figure 2 is an enlarged fragmentary sectional view taken on the line2--2 of Figure 1;

Figure 3 is a side elevational view of the scaffold horse in a folded orcollapsed position, and

Figure 4 is an enlarged sectional View taken on the line d4l of Figure1.

Referring now to the drawing in detail, wherein for the purpose ofillustration I have disclosed a preferred embodiment of the invention,the numeral 5 represents a substantially inverted U-shaped bodypreferably circular in cross section and having a Ushaped saddle 6formed at the center of its upper horizontal portion and extendingdownwardly therefrom.

The upper flat ends I and 8 of a substantially U-shaped forward legmember 9 are respectively pivotally connected by rivets or the like itbetween a pair of spaced parallel horizontal ears ll extending outwardlyfrom a guide sleeve i2 and a similar pair of spaced parallel horizontalears l3 extending outwardly from a second guide sleeve 14, said guidesleeves being ovate-oblong in cross section whereby said downwardlyextending arms l5 and N5 of body 5 are adjustable therein.

Openings or slots ll are provided in said guide sleeves l2 and M betweensaid pairs of parallel ears H and I3 through which extends the forwardlyprojecting vertical edges of dogs l8 and id of said ends I and 8 of leg9, said dogs adapted to fit comfortably in a plurality of vertical dogengaging recesses 20 and 21 in the outer periphery of said respectivearms l5 and I6 of body 5 whereby said [body is adjustable vertically.

Extending outwardly from guide sleeves l2 and Hi respectively and onopposite sides of said sleeves from the pairs of parallel ears I! and I3are pairs of spaced parallel horizontal ears 22 and 23 between which theupper fiat ends 24 and 25 of a substantially U-shaped rear leg 26 arepivotally connected as at 20.

The upper inclined edges 21 and 28 of said ears 24 and 25 are adapted tobear against said sleeves l2 and I4 respectively when the legs are in anormal position as shown in Figure 1.

To collapse the device the legs 9 and 26 are swung inwardly toward eachother against the arms i5 and N5 of the body 5 as shown in Fig- 'ure 3.

The U-shaped saddle 6 in body 5 is designed specifically to hold one endof a beam for supporting the beam between two horses. By using fourhorses in this arrangement with a beam between each set of two horses,planks can be laid transversely across these beams to make a completescaffold flooring adjustable at various heights.

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understanding of thedevice will be quite apparent to those skilled in this art. A moredetailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain change fully comprehended by the spirit of theinvention as herein described and the scope of the appended claims.

I claim:

1. A horse of the class described comprising an inverted substantiallyU-shaped body having a downwardly extending saddle at the upper endthereof adapted to receive one end of a beam, a pair of guide sleeves inwhich the lower ends of said body are slidable vertically, a pair ofU-shaped legs, the upper ends of said legs pivotally connected to saidsleeves, and means carried by the legs and adapted to lockably adjustthe lower ends of said body in the sleeves.

2. A horse of the class described comprising an inverted substantiallyU-shaped body having a downwardly extending saddle at the upper endthereof adapted to receive one end of a beam, a pair of guide sleeves inwhich the lower ends of said body are adjustable vertically, a pair ofspaced parallel ears extending outwardly from one side of each of saidsleeves, a U-shaped forward leg, the upper ends of said leg pivotallyconnected between said ears, a second pair of spaced parallel earsextending outwardly from the sleeves at diametrically opposite sides ofsaid sleeves from the first mentioned cars, a U-shaped rear leg, theupper ends of said rear leg pivotally connected between said second pairof spaced parallel ears, and means carried by said legs adapted tolockably adjust the lower ends of said body vertically in said sleeves.

3. A horse of the class described comprising an inverted substantiallyU-shaped tubular body having a downwardly extending saddle at the centerand upper end of said body, said saddle adapted to receive one end of abeam, a pair of guide sleeves in which the lower ends of said body areadjustable vertically, a pair of spaced parallel ears extendingoutwardly from one side of each of said sleeves, a, U-shaped forwardleg, the upper ends of said leg pivotally connected between said pair ofears, outwardly projecting dogs formed at the upper ends of said forwardleg, said body having a plurality of vertical recesses in its lower endsadapted for engagement by said dogs whereby said lower ends of said bodyare adjustable vertically in said sleeves, a second pair of parallq earsextending outwardly from said sleeves at diametrically opposite sides ofaid sleeves from the first mentioned ears, and a U-shaped rear leg, theupper ends of said rear leg pivotally connected between said second pairof parallel ears.

4. A scafiold horse comprising an inverted substantially U-shapedtubular body having a downwardly extending ofiset at its upper portionforming a saddle adapted to receive one end of a beam, a pair ofovate-oblong guide sleeves in which the lower ends of the body areslidable vertically, U-shaped front and rear legs pivoted atdiametrically opposite sides of said sleeves, the pivoted ends of one ofsaid legs bearing against the sleeve when the said one leg is swungoutwardly from the body, said body having vertically spaced openings inits lower ends and said sleeves having an opening selectivelyregistrable with said openings in the body, and an inwardly projectingdog on the pivoted ends of the other of said legs and adapted forengagement in said openings to lock the body in vertically adjustedposition.
